Intro Okay here is a Noob proof tutorial by me base on what I have read on various threads. Note: That I do not have gateway yet, but want to make sure that everybody include myself get this right. Note: This is a collaboration work by members not my professional guide. Warning!!!!! : This is only base on what I read, it still need to be modify by other member. Edit: people are reported that they are successfully updated their system through these steps. Warning!!: Update do not add any features to the system until GW team update it. Always check the Firmware version before you attempt to upgrade! Note!!!!: This is a beta release of Gateway 2.0b, Something may goes wrong even if you fellow these steps !!! If you do not wish to risk your system just stop at step 12 and wait for Gateway to release a stable version of FW. Note!!!!: There is really no need to update the firmware to 7.1 right now other than being able to play cartridges that require 5+ firmware. Disclaimer: Do it at your own risk System info. The system is brand new 3DS XL with FW: 4.4.0-10u Note: Any FW between 4.1-4.5 would work. You do not need to update to latest FW: 4.5 to use Gateway 2.0b Steps NOTE: For the old Gateway user just skip to step 7th Edit:If you do not wish to upgrade your emuNAND just stop at step 12th 1st: boot up the system setup username, turn off wifi, skip WIFI setup, then go to setting check the FW ver. 2nd: Connect your mircoSDcard, then Copy files from Blue Card (R4i) folder to the Root of a fat 32 formatted Micro SD Card (small SD card not the one in your 3ds)--> put the Micro Sd Card in your blue gateway card--> put it in your 3DS. 3rd: Run Gateway installer 4th: Press A to install then Press A to power down or Home to return to main menu 5th: Copy Launcher.dat from GW Release to the root of the SD card from the 3DS 6th: Boot the Gateway mode by going through Setting-> other setting -> profile-> Hold L-> Nintendo DS profile. Note: press L is to launch GUI (gateway user interface)with out L your 3ds will boot directly boot in to Gateway mode (regular 3ds menu where you can play rom. 7th: In GUI select the "BACKUP SYSTEM NAND" option (need at least 1 GB free space of 3ds SD card) 8th: Turn off the system- > takeout your 3DS SD card backup your newly created .NAND on your PC. 9th: After copy the file put your 3DS Sd card back into your 3DS. 10th: Boot up GUI-> run the Format emuNAND. Not sure what will happen to the system it may be power off or it may just boot into gateway mode. 11th: close your 3DS and takeout your Sd card-> on your computer drive you will see that half of your memory space is gone. 12th: put your 3DS SD card back in to your 3ds---> Boot up GUI again this time run Gateway mode. Edit: you should also move either the icons around, or create a folder, to make the emuNAND visibly different from the realNAND. by MadButch 13th: Go to setting check "GW3D" label in the system version number in the System Settings application. 14th: Enter into WiFi settings and set up a connection. Accept the TOS (term of services) Note: some people report that they accidentally update their readNAND instead of their emuNAND after setting the wifi connection. 15th: reboot your system go to setting internet setting Deleted your wifi setting. (may not need to do this step) . gix222 noted that the system does not remember your WiFi setting from emuNAND in realNAND. So just skip this step. 16th:Turn off your 3DS--> reboot 3ds in to gateway mode again.-> go to setting check again that GW3D" label in the system version number.
